Data Sheet

Pressure transmitter Type MBS 1700 and MBS 1750

For general purpose

The compact pressure transmitters MBS 1700 and MBS 1750 are designed for use as a general purpose transmitter, and oers a reliable pressure measurement, even under harsh environmental conditions.

The version MBS 1750 with integrated pulsesnubber is designed for use in applications with severe medium inuences like cavitation, liquid hammer or pressure peaks and oers a reliable pressure measurement, even under harsh environmental conditions.

Excellent vibration stability, robust construction, and a high degree of EMC / EMI protection equip the pressure transmitter to meet the most stringent industrial requirements.

Features

• Enslosure and wetted parts of acid-resistant stainless steel (AISI 316L)

• Pressure ranges in relative (gauge) from 0 – 25 bar

• Output signal: 4 – 20 mA

• Pressure connections:

◦ G 1/4A & G 1/2A EN837 (MBS 1700) ◦ G 1/4 DIN 3852-E, Gasket DIN 3869-15 (MBS

1750)

• Fully digitally compensated

Application

Application and media conditions (MBS 1750)

Figure 1: MBS 1750

Application

Cavitation, liquid hammer and pressure peaks may occur in liquid lled systems with changes in ow velocity, e.g. fast closing of a valve or pump starts and stops. The problem may occur on the inlet and outlet side, even at rather low operating pressures.

Media condition

Clogging of the nozzle may occur in liquids containing particles. Mounting the transmitter in an upright position minimizes the risk of clogging, because the ow in the nozzle is limited to the start-up period until the dead volume behind the nozzle orice is lled. The media viscosity has only little eect on the response time. Even at a viscosities up to 100 cSt, the response time will not exceed 4 ms.
